Does anybody else besides me think that the Flood may be based off of the alien from The Thing? Actually I think that the Thing is worse than the Flood.
Alot of thing in Halo are based off other things. Watch Starship Troopers the movie and you’ll see where bungie got thier marines from in Halo CE. Also the idea for the wraith. In starship troopers there were these giant bugs that shot plasma mortars out thier back end.
